IPS is the panel type. You have various different type of panels, for example also VA and TN. IPS allows more life-like and natural colors and great viewing angles. VA panels have higher contrast ratio's and TN panels are the fastest of them all with minimal response time but less color depth and poor viewing angles. 4k is ambiguous and may refer to 3840 x 2160 or 4096 x 2160, or potentially others. UHD (in this context) refers to 3840 x 2160 and nothing else. This resolution may be called 4k. QHD =[Quad HD] refers to 2560 x 1440p pixels at a16x9 aspect ratio, four times that of 720p standard high definition and nothing else. Ultra wide QHD boosts the horizontal pixels to 3440 for a 21x9 aspect ratio. Ultra wide 21x9 is to much for gaming, 1440p is better
Sorry, there was a problem. Please try again later.Just compare specs, I put two tabs with the monitors side by side on my screen, and go through, well this one has better contrasts, but this one has better response time. Or whatever. Just compare specs, the model numbers are basically irreverent.
Sorry, there was a problem. Please try again later.4K = UHD. 2k or 1440P = QHD. If you are Purchasing a 4k UHD Monitor you better have a very High End Graphics Card and Processor or your Frames per a second will fall below 30 FPS with makes most games difficult to play. You can purchase 1440P/QHD and get away with $200 RX480 or GTX 1060 $249 Video Card.
